Specification of letters Patent.

Patented Apr. 10, 191%.

Application filed January 27, 1916. Serial No. 74,65.

To all whom it may concern:

Be it known that I, JAMES D. KING, citizen of the United States, residing at Meridian, Mississippi, have invented certain new and useful Improvements in Safety Devices for Railway-Cars, of which the following is a specification.

My invention is an improvement on the patent granted to Benjamin Hoover, April 6, 1915, No. 1134335, and is designed to simplify the construction shown and described in said patent.

In the accompanying drawing,

Figure 1 is a front elevation of my improved and simplified device;

Fig. 2 is a top view, and

Fig. 3 an end view.

The device belongs to that type in which the derailment of the train will open the air line and apply the brakes so as to bring the train quickly to a standstill. I utilize in carrying out my invention a brake controlling train pipe having an opening closed by a valve normally with an oscillating arm holding the valve and adapted to be moved on any derailment or other unusual condition to release the valve and by reducing the pressure in the air line to apply the brakes in the usual manner. Instead of the more complex structure of the Hoover patent I use a vertically arranged spindle having an upper hooked end engaging the controlling valve, the lower end of the spindle carrying a lever through which the spindle is moved by some suitable connection which in turn will be operated by any unusual position assumed by the train, as by derailment or the movement of the body of the car in relation to the trucks or the trucks in relation to the rails, such a connection being shown in the Hoover patent and capable of assuming many forms, the only requirement being that there shall be a certain amount of lost motion to prevent the valve being opened in the ordinary oscillations of the parts of the train when going over uneven rails or around curves, it being understood that only an abnormal displacement of the parts shall operate to oscillate the spindle and release the valve.

In the accompanying drawings, A is the air pipe and B the valve, the valve as shown in Fig. 3 being pivoted at a, to ears I) and closing an opening 0 from the train pipe, suitable rubber gaskets (Z forming an airtight connection between the valve and the opening in the pipe. A vertically arranged spindle e is supported in a bracket f projecting from the pipe line and this has a hooked end 9 which is formed with a knife edge as at h, Fig. 1, engaging a groove in the upper face of a projection 2', extending from the valve on the side opposite the pivot point of said valve. The projection i has its upper face rounded on the edges so that as soon as the knife edge leaves the groove it will slide readily out of engagement with the valve and allow it to open quickly. The spindle has a slotted arm 70 fastened to its lower end and by the turning of this arm the spindle is disengaged from the valve which is allowed to open under the pressure of the air within the pipe.

Any suitable operating means may be held by the arm is, through its slot and be placed in connection with any part of the train so as to be actuated by any abnormal move ment of the parts to turn the arm is, and through it the spindle c, and thus allow the valve to open. It will be observed that this makes a very simple construction, the pipe sections being made in one piece with the support for the valve and the support for the spindle; the valve constitutes but a single piece, the spindle a single piece and the arm is connected thereto by a squared opening with a nut locked to the lower end of the spindle.

What I claim is:

1. In a safety attachment for railway cars, a brake controlling train pipe, a pivoted valve closing an opening in the same, a member having one end directly engaging said valve to hold it closed, and means connected to the opposite end for oscillating said member to positively disengage it from the valve to allow the valve to open, substantially as described.

2. In a safety attachment for railway cars, a brake controlling train pipe, a valve closing an opening therein, a vertically arranged spindle having a hooked end directly engaging and holding the valve closed and means for oscillating the spindle to allow the valve to open, substantially as described. connected to said spindle for oscillating it,

3. In a safety device for railway ars, a substantially as described. in pipe section having formed thereon ears, In testimony whereof, I affix my signature a valve pivoted betweenasaid ears and 010s in presence of two Witnesses. 5 ing an opening in the pipe section, a bracket JAMES DAVID KING.

also carried by the pipe section and an oseil- Witnesses: lating spindle carried thereby having a F. L. MIDDLETON, hooked end engaging the valve, and an arm BENNETT S. J ONES.
